They feature three legs that secure the DiamondFIRE electrode by chance. This allows for excellent heat transfer and helps create more turbulence in the cylinder. It has been proven that the patented DiamondFIRE side wire works to increase power, reduce fuel consumption, and improve hydrocarbon emissions in long-term use. Additionally, the unique ground electrode and full-size center electrode also provide optimal performance guaranteed for five years or 100,000 miles.
